Rakosi Orthodontic Diagnosis Pdf Download
craniofacial anatomy and orthodontic diagnosis share many common features. the essential features of the craniofacial complex are best defined as the seven basic bony structures of the skull (with their associated soft tissues) and their relationships to each other. facial growth is a complex process that involves the growth of the cranial bones, the muscles of facial expression, the soft tissues of the face, and the growth of the teeth.
understanding the facial growth process and the basis for craniofacial growth abnormalities is the key to understanding the diagnosis and treatment of such malocclusions. craniofacial growth abnormalities are caused by abnormal development and interaction of the bones and muscles of the face, and are generally classified as either dentofacial or craniofacial.
orthodontics is the study of malocclusions and the diagnosis and treatment of the related malocclusions. there are many diagnostic methods that are used to determine the presence of a malocclusion. however, the most valuable and accurate diagnostic method is the cephalometric radiograph. this radiograph is based on a superimposed model of the craniofacial complex with the teeth located in their normal position. based on the information obtained from the cephalometric radiograph, the dentist or orthodontist can determine the presence, cause, and extent of the malocclusion.
orthodontic treatment is usually divided into two stages, the presurgical stage and the postsurgical stage. the presurgical stage consists of accurate diagnosis, including completion of the cephalometric radiograph, and the determination of the need for surgical intervention. the postsurgical stage consists of the insertion of fixed or removable orthodontic appliances and the correction of any initial orthodontic and occlusal problems.
the present study aimed to evaluate the effect of orthodontic treatment on the airway patency in patients with skeletal class iii malocclusion. the study compared the cephalometric radiographs of 57 patients (mean age, 14.5 years; standard deviation, 3.1 years) with a skeletal class iii malocclusion, obtained before and after orthodontic treatment. cephalometric parameters were measured using the software ctad for windows. the results revealed that the intraclass correlation coefficient for the variables was 0.99, and the paired t-test showed a statistically significant decrease in the apnea-hypopnea index (ahi) after orthodontic treatment. a statistically significant decrease was observed in the ahi, the lowest arterial oxygen saturation level (lsao2), and the lowest arterial oxygen saturation level (lsao2) in the group treated with orthodontic treatment compared with the control group. these findings indicate that the cephalometric variables, which included the ahi, lsao2, and the ahi, can be used as diagnostic and prognostic indicators of treatment outcomes in patients with skeletal class iii malocclusion. the ahi, lsao2, and the ahi in the patients with skeletal class iii malocclusion can be used as diagnostic and prognostic indicators of treatment outcomes in patients with skeletal class iii malocclusion. the decrease in ahi, lsao2, and ahi after orthodontic treatment indicates the therapeutic effect of the treatment.
the article reports the clinical and radiological studies of orthodontic management of a patient with dental characteristics resembling that of cleidocranial dysplasia. intensive study and treatment planning and preparation were undertaken, and, following these, treatment progress was very promising.
